The remnants of Tropical Storm Blanca are expected to bring cloudy and muggy weather to the San Diego area Tuesday, along with potentially heavy rainfall inland.

Increased moisture from the unsettled system is expected to bring showers and isolated thunderstorms near the mountains and deserts tonight through Wednesday, according to the National Weather Service. Some areas near the mountains could get a few tenths of an inch of rain, while highland locations might receive around a quarter of an inch.

Forecasters said thunderstorms, if they materialize, could produce heavy rainfall in the mountains and deserts Tuesday afternoon.

The tail end of Blanca, now downgraded to a tropical depression, is also expected to cool inland areas through Wednesday.

Highs Tuesday are expected to be 75 to 80 degrees near the coast, 85 to 90 degrees inland, 90 to 95 in the valleys, 77 to 83 degrees in the mountains and 86 to 91 degrees in the deserts, according to the weather service.

Most of the precipitation is expected to end Tuesday evening.

Forecasters said the cloud cover and humidity would begin to exit the region by Wednesday evening. A trough of low pressure is then expected to move inland through the state, bringing dryer conditions.
